A log that has been carved to resemble a penis - male sex organ- in the pagan worship of Saturnalia (Now know as Christ's mass) - for the GOD of excess & fertility GOD YULE.
The log is set to burn for 7 day's of the celebration with sometimes human sacrifices in this food, drink & sex (Homo-sexual encounters allowed) orgy, on the darkest days of the year in the winter- The only day master becomes slave- slave becomes master.

Peter asked "Is that a Yule log in your pocket- long, round, hard, & on fire...or are you just happy to see me or both..."
Dick said "Yes- would you like to worship it cause if I side it into your man holes...it will burn for 7day's- it wouldn't splinter and you better be clean cause I don't want the (Shit end) of the stick after..."

one definition may be: The first large defecation on or around Christmas that occurs when the following conditions are met 1. in a state of euphoria from various ingested substances 2. large quantities of heavy food have been consumed 3. on Christmas vacation 4. great sense of relief and renewed optimism follow the event

Tidings and joy everyone, I have broken out the yule log, let's rejoice!
